1,4-Benzoxazine derivatives representable by the general formula; ##STR1## wherein R.sup.1 and R.sup.2 independently stand for hydrogen, halogen atom, nitro group, an optionally substituted lower alkyl group, an optionally substituted amino group, an optionally substituted hydroxyl group, a lower alkoxycarbonyl group, or when R.sup.1 and R.sup.2 are adjacent to each other,R.sup.1 and R.sup.2 combinedly stand for a ring representable by --CH.sub.2).sub.m (wherein m denotes an integer of 3 to 5) or --O--CH.sub.2).sub.n O-- (wherein n denotes an integer of 1 to 3),R.sup.3 stands for hydrogen or a lower alkyl group,R.sup.4 and R.sup.5 independently stand for hydrogen, halogen atom, an optionally substituted lower alkyl group or an optionally substituted hydroxyl group, andA stands for an alkylene groupor acid addition salts thereof, are useful as prophylactic or therapeutic drugs for, among others, hypertension or ischemic dieases.
摘要:
A thiazolidinedione derivative of the general formula: ##STR1## wherein X is an oxygen or sulfur atom, R.sup.1 and R.sup.2 each independently is hydrogen or a hydrocarbon residue which may optionally be substituted and R.sup.1 and R.sup.2 may jointly, together with the oxazole or thiazole ring, form a condensed ring and A is a lower alkylene group; or a salt thereof, are novel compounds, which exhibit in mammals blood sugar- and lipid-lowering activity, and are of value as a therapeutic agent for diabetes and/or therapeutic agent for hyperlipemia.
